Media Factory began promoting a new series by author So Nanauami, and it totally gets points for being unique. The series is titled Isekai Onsen ni Tensei Shita Ore no Kounou ga Tondemosugi – Anta no Naka ga Kimochi li Wake Janai n Desukedo!? (I Was Reincarnated as a Hot Spring in an Alternate World, and I'm Way Too Effective – It's Not Like it Feels Good Because I'm Inside of You or Anything!?).

The story is about a high school student named Atami Kusatsu, and his ill fated trip to a rural hot spring. As usual, he accidently dies and is reincarnated in an alternate world. But, instead of becoming a hero, Atami is reincarnated as a beautiful hot spring with magical healing properties.

The series is basically this pic, but the water is the protag.

Women just love to visit the watery Atami to take dips inside of him. Media Factory teases that Atami's water "gets hard and milky" when the ladies dive into him.
